Myopia, or nearsightedness, is one of the most common eyesight problems. People with this condition can't focus their eyesight on far-away objects, making them appear blurry. Nearsightedness affects about 25 percent of all people in the United States, according to the National Eye Institute

Answer:
There are many eye related problems and defects of the eye, the main few are briefly discussed below:
Defects of the eye:
Myopia: (nearsightedness) This is a defect of vision in which far objects appear blurred but near objects are seen clearly. The image is focused in front of the retina rather than on it usually because the eyeball is too long or the refractive power of the eye’s lens too strong. Myopia can be corrected by wearing glasses/contacts with concave lenses these help to focus the image on the retina.
Hyperopia: (farsightedness) This is a defect of vision in which there is difficulty with near vision but far objects can be seen easily. The image is focused behind the retina rather than upon it. This occurs when the eyeball is too short or the refractive power of the lens is too weak. Hyperopia can be corrected by wearing glasses/contacts that contain convex lenses.
